arXiv:2606.00183v1 Announce Type: new Abstract: Tree search is a central abstraction behind many language-agent reasoning and decision-making tasks: agents must explore actions, remember failures, and backtrack toward promising alternatives. Yet, we lack a theoretical understanding of how transformer-based policies acquire such search capabilities from the training dynamics of reinforcement learning (RL). We study this question in a stochastic $k$-ary tree environment, where an agentic transformer observes only its trajectory history through interaction and receives a terminal reward for reach
The proliferation of more capable large language models and growing interest in autonomous AI agents drives research into understanding and improving their decision-making capabilities.
This research provides a theoretical foundation for how transformer-based AI agents can learn complex search behaviors, directly impacting the development of more reliable and effective autonomous systems.
We gain a deeper understanding of the learning mechanisms within agentic transformers, potentially enabling more robust designs for AI that can plan and adapt in dynamic environments.
